FAfiTENER-SETTING MACHINE.

Application flied May 14,

To all 111710771 it may concern:

Be it known that l, PERLEY R. GLAss, a. citizen of the United States,residing"at l i ayland, in the county of Middlesex and tate ofMassachusetts, h ve invented certain improvements in Fastener-Settingchines, of which the followingdescription, in connection with theaccompanying drawings, is a. specification, like reference characters onthe drawings indicating like parts in the several figures.

This invention relates to fastener-setting machines and more especiallyto machines for setting lacing-hooks. The majority of machines forsetting lacing-hooks are provided with mechanism for feeding the workstep by step to space the hooks, and it is with such machines that thepresent inventtion is more particularly concerned.

In a general sense an object of the invention is to improve theorganization of such machines so as to insure greater accuracy, tominimize vibration and to increase the capacity for speed of operation.More specifically an object is to control and operate the hook-engagingdevices so to insure accurate work at high speed. In this connection afeature of the invention consists in novel and improved means forcoupling the hook sustaining member and the clenching tool to areciprocatory acuator in such manner that a single motion of the latterwill retract the clenching tool and move the hook-sustaining memb rlaterally to clear the throat of the clenched hook. Another featureconsists in organizing; the aforesaid hook-sustaining member, clench--ing tool, and their common actuating mechanism in such manner that asingle motion of the actuator willimpart the final clenching motion andthe throat-clearing motion. 7

iVhen. as in the machine illustrated by the accompanying drawings, thehook-sustaining member has a carrying motion for transferring the hooksfrom a source of supply to the work such carrying motion is additionalto but distinct from its throatclearingmction. Former constructionsdesigned to afford both these motions have been more or less deficientas to; speed of operation, capacity to withstand the'clench- L ngstresses, or accuracy of registration with the source of supply andtheclenching tool because of mechanical dlfliculties which .ating themin uniso'n, and aportionofv 1821. Serial No. 469,665.

are wellknown but which have not been solved heretofore as well as theymight Accordingly an object of the invention is to improve'theconstruction of this mechanism in hook-setting machines. A featureof this part of the invention consists in a construction such thatangular motions are wholly eliminated from the hook-sustaining memberand from the members that engage it-to impart the aforesaid carryingmotion and clearing motion, and such that said motions are imparted bytwo members arranged to execute simple rectilinear motion transverselyone to the other.

Other features of the invention are hereinafter described and claimedand are illustrated by the accompanying drawings.

Referring to the drawings, which illustrate a preferred embodiment of.the' invention,

t The general organization of the machine here represented is similar insome respects to that illustrated in my application Serial No. 323,164,filed September 11, 1919. For example, the punching and feedingmechanisms are identical with those of the aforesaid application.Furthermore the construction of the presser-foot is similar in mostrespects to that shown in said application. The hopper for thelacing-hooks, and the mechanism for feeding the hooks out of the hopperare herein shown as embodying a construction similar in many respects tothat illustrated in United States Letters Patent 811,839 grantedFebruary 6, 1906 on my application. Accordingly the features ofconstruction and operation that are common to this present case and tothe aforesaid'cases need not be so fully described herein as 7 mightotherwise be necessary since they are sufficiently described in theearlier cases.

Before describing the details ofconstruction it may be well to considerthe general organization of the machine. An article of worksuch as ashoe-quarter is placed right side up on a work-support and is heldthere- I on by a Presser-foot that bearsdown continuously while the workis being fed as well as while 1t is at rest; A punch-block is supportedrigidly above the work but to all intents and purposes in contacttherewith.

The clenchingtool is arranged below the work and, is-provided'with atubular pilot that punches the work andthen feeds the latter tohook-receiving position. The lacing-hooks are inserted into the workfromabove by a hook-carrier to which they are supplied one a time. The hookis placed on the carr er 1n suchposition that its head is uppermost, thebarrel portion of the hook extending downwardly from the carrier. lVhenthe hook-carrier descends the barrel of the hook encircles the pilot ofthe clenching tool and is ultimately clenched against the under side ofthe work by the clenching surface at the base of the pilot. Theclenching tool is then moved downwardly to withdraw it from the hook,and at the same time the hook-carrier is moved laterally to clear thethroat of the hook before it rises to receive another hook. The carrierthen rises until it is in registration with the delivery end of theraceway, and while this is occurring the clenching tool moves to theright preparatory to punching another hole in the work. While thehook-carrier is in its upper position it is moved to the rear until itis close to or actually touches the delivery end of the raceway, thehook-transferring device meanwhile advancing toward the hook-carrier totransfer the leading hook to the latter. This briefly describes thecycle of the hook-setting instrumentalities.

An. article of work such as that indicated at 10 in Fig. 5 is laid onthe work-support 11 and is held thereon by a presser-foot 12 that bearsdown continuously. The worksupport is provided with a slot 13 throughwhich the clenching tool 14; risesv and along which it moves to feed thework. This tool is carried by a plunger 15 that is reciprocated up anddown bymecha'nism.(see Fig. 2) including toggle members 16, a link 17,an operating lever 18 and a cam 19. This cam is afiixed to a shaft 20and moves the toggle members to the left from the initial position shownby Fig. 2 untilthe knee of the togglehas passed slightly beyond thedead-center position. This motion causes the tubular pilot portion 21 ofthe toolto punch a hole through the work, the tool at .motion of thetoggle beyond its dead-center position relieving the punching pressureagainst the punch-block so that the tool may be readily moved laterallyto feed the work. 7

The punch-block is rigidly sustained by a plunger 23, toggle members 24,24:, link 25, lever 26, stop screw 2'? and abutment 28. A spring 29attachedto an arm of the lever 26 maintains the parts normally in thepositions shown by Fig. 2 but permits the lever to be moved by atreadle-rod 30 so as to lift the punch-block preparatory to present ingand removing an article of work.

The plunger 1:) slides in a bearing afforded by a carriage 31, saidcarriage being arsh af 3a. This rockshaft is oscillated With 7 Inn.

a variable amplitude of motion by suitable mechanism including a cam 35on the shaft 20. The carriage 31 is thereby reciprocated from theposition shown by Fig. 5 to that shown by Fig. 6 and vice versa.iVhenever the feeding mechanism is adjusted to change the length of thefeeding steps a corresponding change is made in the position of thepunch-block so that the latter will always stand in registration withthe punching tool when the latter is executing its punching motion. Forthis purpose the plunger 23 that carries the punch-block i. arranged toslide in an adjustable bearing member 36, suitable connections includinga lever 37 causing the bearing member to slide on a stationarysupporting stud 38 whenever a change is made in the regulation of thefeeding mechanism. h/Techanism embodying substantially the sameconstruction as this is more fully described in my application SerialNo. 323,164 above referred to.

The presser-foot 12 is also carried by the plunger 23 but is movablerelatively to the plunger so that it may maintain pressure on the workirrespective of the position at which the plunger is rigidly sustained.The presser-foot has sliding connection with the plunger and is engaged.lby a finger 89 formed on a member that includes a barrel 40 in which acompression spring 41 is en closed. The member 39, 40 is connected tothe plunger 23 by a pivot screw 42. A fol lower 43 projects through thelower end of the barrel portion 40 so as to bear on an ear 44 of theplunger, the spring 41 being arranged to bear on the upper end of thefollower and against a plug 45 in the upper end of the barrel portionand thus to maintain downward pressure of the finger 39 on thepresser-foot.

During the inserting and clenching operation a lacing-hook is sustainedby a member comprising a head 46 and a stem 47. The construction of thismember is shown best by Fig. 8. Since, according to the illus .tratedembodiment .of the invention, the hook-sustaining member, rather thanthe work, is moved to insert the lacing-hook, said member is connectedto and carried by a plunger 48. The lower end of this plunger is formedwith grooves to receive, guide and'brace flanges formed on the head 46,and is further provided with a trans verse hole 49 in which the stem 47bears. The plunger 48 is reciprocated by a bellcrank lever having arms50 and 51. These arms are arranged on a pivot stud 52 common to both andare rigidly but adjustably connected to each other. The arm 5l-is forkedat its lower end'so as to straddle a cam 53 carried 'by the shaft 20.Although the being thus made for registering the hook-sustaining memberwith the raceway by which hooks are supplied, to it. As shown by Figs. 1and 4 the forward end of the arm 50 forked and straddles a block 54.This block is carried by a sleeve through which the plunger 48 extendsloosely. Downward movement of the sleeve is transmitted positively tothe plunger by nuts 56 threaded on the plunger but upward movement ofthe sleeve is transmitted by; a compression spring 57 to a collar 58affixed to the plunger. Referring to Fig. 2, an ear 59 projecting fromthe plunger 48 abuts against a set-screw 60 while the arm 50 is rising,the set-screw thus serving to arrest the plunger at any desired positionbefore the arm has reached the upper limit of its motion. The head 46 ofthe hook-sustaining member may thus be registered relatively to thedelivery end of the raceway 61 as shown by Figs. 5 and 13.hook-supplying mechanism it will be well to designate the various partsof a lacinghook so that the terms will be clearly understood. I Asindicated in Fig. 12, the lacinghook comprises a barrelportion 62,shoulder 63, a neck 64 andhead 65, the space between the shoulder andthe head being hereinafter referred to as the throat. lteferring toFigs. 9, 10 and 11 the lacinghooks gravitate along the raceway from leftto right, the hook-supporting strip 61 0c cupying the throats of thehooks, and a guard strip 66 being arranged to bear on the barrelportions so as to keep the hooks on the supporting strip 61. ris thehooks gravitate in the raceway they slide sidewise,

their necks being guided by one edge of the strip 61. Although theraceway may have any desired bends or twists between its receiving endand its delivery end the latter is substantially horizontal and standsso that the hooks are supported by their heads as shown by Fig. 13. I

The end-edge 67 of the raceway is sul stautially at right angles to thelongitudinal edge onwhich the necks of the hook slide To facilitate thedescription of theand isin registration with the hook-en-fl gagingflange of the hook-sustaining memher. The leading hook in the racewayadvances sidewise until it reaches the posi 'on indicated at 68 in Fig.9 in whichposition its neck has passed'beyond the corner formed by theedge 67 and the edge that leads the hooks thereto,although one side ofits head overlaps said corner of thestrip .61 (see :12) Tn this positionthe leading hook is in registration with a transferring member 69 bywhich it is subsequently transferred to the member 46. The hook isarrested in this position by a stationary abutment 0 which, inconjunction with the end or edge 67 of the raceway, forms a chan- De 4hr ugh hich the neck ook passes as the hook is being transferred to thecarrier 46. Although the hooks change direction at the aforesaid cornerof the raceway strip they do not turn, but are pre vented from turningand otherwise controlled by a yielding hook-supporting mem ber 71 thatinitially constitutes an extension of the raceway and maintains thethroat of the hook at the level of the hook-sustain ing flange of thecarrier 46 As shown by Figs. 9 and the member 71 is in contact with theedge 67 of the raceway and is flush relatively to the upper and lowersurfaces and the rear edge of the raceway so that the greater part'ofthe head of the hook will slide along and be supported thereby after ithas passed the edge 67. The supporting clench the barrel of the hook.

member 71 is mounted on a pivot member 72 and is normally held inhook-receiving position by a compression spring 739 The channel 74 isslightly wider than the neck 64 of the hook but not so wide as the headofthe hook. The transferring member 69 advances through the channel 74,thereby separating the leading hook from the next hookand causing theneck of the advancing hook to deflect the supporting member 71, whichswings to the right and clears the neck entirely before the latter haspassed out of the channel. While the hook is passing through the channelone side, of its head continues to be supported by the delivery end ofthe raceway while, on the opposite side of the channel, the head of thehook slides from the member 71 to alip 75 formed on the abutment 70. Themovable member 71 constitutes a floating sup port by which the head ofthe hook is carried across the gap between the aforesaid corner of thestrip 61 and the lip 75.

While'the transferring member 69 is advancing to transfer the hook tothe carrier 46 the latter moves in the opposite direction to receive thehook, the carrier finally reaching a position close to or in contactwith the dehvery end of the raceway and the lip 75 as shown by Fig. 11.When the hook is lodged on the carrier as shown by Figs. 11 and 7 itsneck occupies a notch 7 6 formed in the carrier, and the hook ismaintained with its neck in this notch while the carrier descends toinsert and partially As shown by Fig. 7 the hookengaging portion 77 ofthe transferring member is elongated so as to maintain contact with thehook until the latter has been clenched. When the clenching operationhas been partially effected by the complete downward movement of thehook-carrier it 1s completed by a slight upward movement of the clenchmgtool 14 due to return movement of the toggle members 16' same time thetransferring member is retracted in theopposite direction to enable thenext hook to advance to the position indicated at 68 in Fig. 9.' Theplunger'4l8 is then raised to lift-the hook-carrier to the level of thedelivery end of the raceway and then the hook-carrier and thetransferring member are again moved toward each other to deposit anotherhook .on the carrier as hereinbefore explained.

The mechanism for operating the hookcarrier and the transferring memberin unison is illustrated best by Fig; 8 and is shown also to some extentby Fig. 2. The stem 47 of the hook-carrier l as flange-andgrooveconnection with a plunger 78 that is 1 arranged to slide in fixedbearings, 79, its lines of motion being transverse to those of theplunger 48. Flanges 80 formed on the stem 47 are inter-engaged withgrooves 81 formed in head carried by the forward end of the plunger 78,these formations serving to maintain. operative connection between theplunger and the hook-carrier and enabling the latter to moveup and downas aforesaid. A compression spring 82-acts against a collar 83 on theplunger 78 to move the hook-carrier to hook-receiving position, themovement of the hook-carrier in the opposite direction being effected bya lever 84 having a boss 85 arranged to act against the rear face of thecollar 88. A set-screw'86 anchored in one of thebearing elements 79 isarranged to arrest the movement of the plunger 78 to the rear so as toprevent the spring S2'fro1n pressing the hook-carrier too forciblyagainst the raceway. The transferring member 69 is'arranged to bereciprocated in lines parallel to those of the plunger 78, and isactuated by an arm 87. A link 88 transmits motion from the lever 18 tothe arm 87. This arm is arranged to swing on a pivot member 89 and itsupper end is forked and arranged to straddle a block 90 carried by andpivotally connected to a block 91. The stem of the transferring member69 extends loosely through a block 91, the block being confined 1 Awasher 95 of soft material such as leather is interposed between thenuts and the hearing element 79 to limit the movement of thetransferring member toward the hook-carrier. Although the block 91 isreciprocated positively in opposite directions its motion toward theleft is transmitted to the, transferring member 69 by the spring 93 sothat the block may continue to move aft-er the transferring memberhasbeen arrested,'but the movement of the block in the opposite direction'is transmitted positively to they transferring member by the collar 92.This reciprocating motion of the block 91 is transmitted to the lever 84by a stud portion 96 (Fig. 3) formed on or attached to the block. Thestud portion 96 works in a slot 97 in the lever 84. This lever ismounted on a fulcrum member 98, and, when moving in a clockwisedirection, continues after the plunger has been arrested. Consequently,during its first stages of motion in the opposite direction there is aperiod of lost motion during which the clenching tool 14 completes theclenching operation as aforesaid. The connection between thetransferring member 69 and the plunger 78 is such that, aside from saidlost motion, these two elements move in unison but in oppositedirections,

the movement of each being yielding in one direction and positive in theopposite direction. Moreover, since these elements are actuated andcontrolled by thelever 18 it follows that the cam 19 not only producesthe punching motion and the final clenching motion of the lower settingtool but also shifts the hook-carrier 46 relatively to the plunger 48and also reciprocates the hooktransferring member 69. i

Fig. 1 includes a disconnectible clutch for driving the cam shaft 20.Any suitable type of clutch may be provlded for this purpose, the typeillustrated being well known and comprising a continuously rotatingdriving member 100 in the form of a pulley. The pulley is looselymounted on the shaft and may be connected to and disconnected from theshaft at will by an axially movable bolt 101 under the control of aplunger 102. The bolt 101 is adapted to slide axially in a collar 103affixed to the shaft and is provided with, a head 104 having an inclinedsurface adapted to coact with the upper end of the plunger. Acompression spring 105 normally raises the plunger into the path of thehead 104,

but when the plunger is drawn down, as by a treadle rod 106, it releasesthe head 104, thus permitting the bolt 101 to establish drivingconnection under the influence of'a spring (not shown) contained. in theclutch. So long as the plunger 102 is held, down the clutch willcontinue to drive the shaft but when it is raised by the spring 105 theclutch is uncoupled in consequence of wedging action of the head 104 onthe plunger.

It is hereinbefore stated that the arms 50' and 51 of the bell-cranklever that operates the hook-inserting plunger are adjustably connectedto each other. The features of construction shown by Fig. 15 provide forsuch relative adjustment and also provide for collective adjustment, oneto correct inreceive a wrench forthis purpose. Colle e: tiveadjustmentof the arms to adapt the machine for thick or thin work is made"possible by eccentricity of the fulcrum stud 52, the fulcrum portionbeing eccentric rela tively to the endportions which bear in the frameof the machine. A handle 112 is fastened to one endof the stud to affordconvenient means for adjusting it. The

handle is provided with an; ear'113 which lies in contact with afiat'face of the frame" and is pressed against the frame by acompression spring 114 so as tomaintain friction suflicient to hold thefulcrum stud in any position 'to whichit may be turned. The spring 114is held under compression by a stud 115 which extends through ,a con}centric slot 116 in the ear and which is screwed or otherwise anchoredin the frame of the machine,
